To read/dump a commercial option rom in a programmer, tell the programmer software the chip is a 27C256 DIP28, and connect programmer pin 28 to option rom pin 1, and leave programmer pin 28 unconnected.
Sample command line for "minipro" on linux, use with a TL866 programmer:
sudo minipro -y -p "27C256 @DIP28" -r myrom.bin
That will read the chip and write the contents to a file named myrom.bin
